3IP161
The B & R Automation 3IP161 is a high-performance System 2005 Controllers module engineered as a programmable I/O processor for demanding industrial automation environments. Designed by B & R Automation, this standalone unit integrates seamlessly into the System 2005 series backplane, delivering real-time control and deterministic performance. With C-UL-US Listed certification, the 3IP161 meets rigorous North American safety and performance standards, ensuring reliable operation in factory floors and process control systems. Its compact design houses significant memory and processing resources, making it suitable for applications requiring rapid signal processing and extensive program storage. Engineers will appreciate its advanced monitoring capabilities and robust hardware platform that support integration with digital and analog I/O, as well as fieldbus networks.
The 3IP161’s technical architecture features 174 KB System RAM dedicated to core functions and 850 KB User RAM for application data, providing ample workspace for complex logic structures. Non-volatile storage includes 512 KB System FlashPROM for firmware retention and 1.5 MB User FlashPROM for program code and configuration, ensuring data integrity through power cycles. A typical instruction cycle time of 0.4 µs underpins fast execution of ladder, structured text, or function block code. Four dedicated status LEDs and four interface LEDs provide immediate visual feedback on module health and network activity. The integrated real-time clock offers externally buffered, 1 s resolution, maintaining accurate timekeeping even during CPU operation.
Operational features include deterministic response to I/O events with a programmable scan cycle tightly coupled to the module’s clock and peripheral interfaces. The 3IP161 supports CAN interface communication for distributed control topologies, enabling up to 127 nodes per bus. With its Module Type: B&R 2005 system module, it accommodates high channel counts without sacrificing cycle times. The built-in status display and programmable diagnostic registers facilitate early fault detection and streamline maintenance. Low CPU load during idle cycles conserves system resources, while high-speed processing ensures minimal jitter for time-critical tasks.
System integration of 3IP161 is straightforward via the System 2005 backplane bus, which provides power, data, and synchronization lines in a single connector. The programmable I/O processor is compatible with B&R’s Automation Studio environment, offering configuration, simulation, and debugging tools. Its design supports hot-swap replacement and field upgrades without system downtime. Ideal for machine building, packaging lines, material handling, and process automation, the 3IP161 module delivers a balance of memory capacity, processing speed, and robust diagnostics to meet the needs of complex industrial applications.
